In order to solve the technical problem, scientific research institutions and scientific personnel of enterprises are continuously exploring and researching to develop various machining methods for grooves in the breathing valve body, and although certain positive effects are achieved, the technical problem which is not overcome in practical application still exists.

Disclosure of Invention

The utility model aims at overcoming the above not enough, provide a reasonable in design, the embedded mold insert of machine-shaping is exempted from to groove in simple structure's a plastics, this embedded mold insert mainly used multiple car breather valve body. The breather valve body is made of high-strength rigid plastic, nylon, ABS and the like through injection molding. The inner hole of the breather valve body is provided with the embedded insert which is formed by combining an outer ring and an inner ring, the inner wall of the outer ring is provided with two steps, an upper step and a lower step, the inner ring is embedded in the lower step to form a groove, the groove meets the design standard, the groove is mainly provided with a spring clamping piece, the technical problem of processing the groove on the breather valve body made of various automobile plastics is solved, the cost is saved, no waste product is produced, and the working efficiency is improved.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a processing forming embedded mold insert is exempted from to ditch groove in plastics, contains breather valve body, embedded mold insert, recess, external screw thread, outer lane, inner circle, spring card piece, the: the breather valve body is mainly made by rigid plastic, and the breather valve body is a cylinder shape, is equipped with the external screw thread on the breather valve body, the breather valve body: the center of the breather valve body is provided with a round hole, an embedded insert is arranged in the round hole, and the breather valve comprises: the embedded insert is formed by combining an outer ring and an inner ring, the inner wall of the outer ring is provided with two steps, an upper step, a lower step and the inner ring are embedded on the lower step to form a groove, and the following steps: a spring clamping sheet is arranged in the groove to form the plastic inner groove machining-free embedded insert.

The technical principle of the utility model is that: the utility model provides a ditch groove is exempted from to process into shaping embedded mold insert in plastics, the breather valve body on multiple car all adopts metal material to process and makes, and at the upper end of breather valve body especially, need process into a recess on the lathe, mainly install a spring card in the recess, and the processing cost is higher. In order to reduce the production cost, the plastic machining is changed, and the plastic machining is generally made of hard materials such as nylon, ABS and the like. In the injection molding machine drawing of patterns in-process, the recess is yielding, because the recess width is great at 1.3mm (millimeter) X degree of depth 2mm (millimeter) processing degree of difficulty, the rejection rate reaches more than 60%, be equipped with an embedded mold insert on cylindrical shape's breather valve body hole, this embedded mold insert is formed by outer lane and inner circle combination, the outer lane inner wall is equipped with two steps, an upper ledge, a lower ledge, the inner circle is inlayed on the lower ledge, form a recess, this recess mainly installs the spring card, the one technological problem of processing the recess on the breather valve body that automobile plastics were made has been solved, and the cost is saved reaches production no waste product, and work efficiency is improved.

The utility model has the advantages that: the utility model provides a processing into shape embedded mold insert is exempted from to groove in plastics, it forms with moulding plastics to adopt high strength rigid plastic, nylon, ABS etc. at breather valve body, be equipped with an embedded mold insert on the breather valve hole, this embedded mold insert is formed by outer lane and inner circle combination, the outer lane inner wall is equipped with two steps, an upper ledge, a lower step, the inner circle is inlayed on the lower step, form a recess, this recess accords with the design standard, this recess mainly installs the spring card, the one technological problem of processing the recess on the automobile breather valve body has been solved, the cost is saved, it does not have the waste product to reach production, and work efficiency is improved.
